The invention relates to an energy-saving type spraying room based on the Internet of Things for automobile bumper processing. The energy-saving type spraying room comprises a paint spraying chamber,an inlet and an outlet; a translation mechanism, a moving block, an air suction hood and an exhaust mechanism are arranged in the paint spraying chamber; the translation mechanism comprises a first translation assembly, a translation plate and a second translation assembly; the first translation assembly comprises a first motor, a buffer block and a first driving shaft; and the exhaust mechanism comprises a first air pipe, a second air pipe, a cleaning box, an exhaust box and a discharging pipe. The energy-saving type spraying room based on the Internet of Things for automobile bumper processing has the advantages that the moving block is driven to move through the translation mechanism so that the air suction hood can suck mist in air at all positions in the paint spraying chamber, and therefore the action range can be widened, and meanwhile, the energy consumption can be reduced; moreover, mist spray particles in the air are absorbed through the exhaust mechanism, and a cleaning assembly is driven by a lifting assembly to clean a filter screen so that the filter screen can be prevented from being blocked; and the ventilation of the exhaust box is ensured so that the power consumption of an exhaust assembly can be reduced, and therefore the energy-saving effect can be achieved.
